Hi Anthony,
Here are a few things I have found. I was testing on a 400DPI, 16800x12000
binary image.
1) While zoomed out so I could see about 50% to 100% of the entire
image, -every time- I removed a rectangular region, it would take 5+ seconds
to "Processing image..."
2) While zoomed in so I could see around 25% to a 3rd of the entire image,
each rectangular remove was pretty fast. The only time I would see the
"Processing Image" prompt, was when I zoomed out a little. If I stayed at
a relatively constant zoom level and just panned around, Remove Rectangle
was pretty fast.
So, if you stay zoomed in, removal is faster.
3) I theorized that turning of AutoCAD Undo, might speed things up, but I
didn't notice much difference.... (UNDO, Control, OFF). I'll have to dig
around for a separate undo setting for Raster Design.
4) It may help to set Image > Options > Memory > Temp file location to the
FASTEST drive you have if you have more than one. Pretty much each image
edit you do enlarges an AECxx.tmp file in that folder. At one point,
after editing that image for 20 minutes or so, I noticed that TMP file was
over 1 GIG in size. Defragmenting your drive may help -a little- too.
A wild theory that I have yet to try is to create a "Ram disk", and point
the Raster Design TEMP folder setting to it. Of course this would only
work if you have extra ram oozing out of your ears. So, for example, if
you have 4 GIGs of ram total, create a Ram disk that is 2-3 gigs in size.
So Raster Design's access to it's AEC TMP file *should* be lightning fast.
One program I know of that creates a RAM disk is called RAMDISKXP if anyone
wants to track it down and try it. (you may need to purchase the product,
and more ram for that matter.) If you only have a Gig or less, I wouldnt
even bother trying this.

Nope - its our (inflexible) requirement that the images stay at 400DPI and
36x24.

Can you reduce the resolution to 200 DPI or less?
That would speed things up.
